How to Claim the 200% Thailand SME Digital Tax Deduction to Upgrade Your Business

It is a government tax incentive that allows qualified small and medium-sized enterprises (SMEs) to deduct 200% of their digital transformation expenses—such as buying new software or cloud services—from their taxable corporate income, dramatically lowering their tax bill.

To qualify under the Thai Revenue Department rules, your company must have a total gross revenue of no more than 50 million THB during the fiscal year, and your registered paid-up capital must not exceed 5 million THB on the last day of that accounting period.

No, standard hardware like laptops or basic office computers do not qualify. The incentive specifically covers enterprise software (like ERPs or CRMs), cloud-based SaaS subscriptions, and smart IoT devices that integrate with automated business systems.

The Thailand Digital Catalog is a government-vetted list managed by the Digital Economy Promotion Agency (depa). By law, you can only claim the 200% tax deduction if the software and the vendor you purchase from are officially registered in this specific catalog.

If you spend 1,000,000 THB on registered software and your corporate tax rate is 20%, a standard deduction saves you 200,000 THB. With the 200% incentive, your deductible expense becomes 2,000,000 THB, saving you 400,000 THB in actual cash. It effectively reduces the software cost by 40%.

The most frequent cause for rejection is vague invoicing. If a tax invoice broadly states 'IT Consulting' or 'Software Services' instead of explicitly naming the specific software product exactly as it appears in the depa Digital Catalog, the claim will be denied.
